2. If you're carrying a load that extends beyond the sides of your vehicle, you don't need to clearly mark it unless it extends more than beyond the rear of the vehicle. A. four inches B. four feet o o O o C. six feet D. eight feet ​

A I believe sorry if I’m wron.

Explanation:

the current is 0.6

voltage ÷ resistance = current

so 12 ÷ 20 = 0.6

the minimum constant speed at which she can catch the train is 2.7 m/s

given:

acceleration = 0.6

time = 4.5 s

to find:

velocity = ?

formula used:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

solution:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

v = 0 + (0.6 × 4.5)

v = 2.7 m/s

the minimum constant speed at which she can catch the train is 2.7 m/s
